Hi There,
I could not edit the original post anymore but I have now solved the problem.
UPDATE 3: In the plugin preloader section the display loading screen was ticked, I really do not know how that happened as I did not tick it myself so it most of happened during the updates, anyway the site is now working fine and I am a happy bunny, lol!
I will leave the post here as I cannot delete it, hopefully it may help others in a similar situation.
Kind Regards
Andrew
